How to merge PDFs safely
Upload the PDFs you want to combine, arrange them in the right order, and click Merge PDF. The tool runs locally in your browser, so the original files stay on your device.
- Rename the output file to match your project or client naming convention.
- Keep the total file size reasonable for faster processing on lower-memory devices.
- Reorder files before merging so the final document reads correctly.
Tip: If a PDF looks out of order after merging, clear the list and re-add files in the desired sequence for a clean pass.
Common PDF merge examples
Invoices and receipts
Combine monthly invoices, receipts, and payment confirmations into one file before sending them to a client or accountant.
Applications and forms
Join an application form, supporting documents, certificates, and ID scans into one ordered PDF package.
Study material
Merge lecture notes, assignments, worksheets, and scanned handouts so the final document is easier to share and review.
Reports and proposals
Attach cover pages, appendices, charts, and signed approvals behind the main report in the exact order readers need.
Before you merge
- Open each source PDF once to confirm it is not password protected or damaged.
- Rename files with numbers such as 01-cover, 02-report, and 03-appendix if you need a fixed order.
- Use smaller files on mobile devices because browser memory is limited.
- Download and review the merged PDF before deleting the original files.
